Britney Spears Through the Years

A classic black-and-white scene from Britney Spears' upcoming MTV documentary, "For the Record," Nov. 30, 2008. "So much has gone on over the last couple of years and there's a lot that people don't know about me that I want them to know," Spears told MTV News in a statement about the special. "I wanted to make this film because I started to feel like I wasn't being seen in the light that I wanted to be seen in. This is an opportunity to set the record straight and talk about what I've been through and where I'm headed."

Beach Bods

Spears bewildered and entertained photographers with her constant antics and lack of clothing. Out and about one summer afternoon, Spears didn't have her swimsuit, but she didn't let that stop her from taking a dip. The struggling singer got a little wet and wild in her undergarments and flashed some photographers a very unflattering view of her bare behind, July 18, 2007.
